The Dollar Tree offers free shipping if items purchased online are shipped to a Dollar Tree brick-and-mortar retail store for pickup. The Dollar Tree also sometimes runs limited-time flat-rate shipping promotions. The Dollar General chain also offers online shopping. As of 2015, the 99 Cents Only and Family Dollar chains do not offer online shopping. It is also possible to search certain e-commerce sites, such as Amazon, with a price filter that restricts displayed items to those that cost 99 cents or less.
